simple-scan not working with canon pixma mx475 / sane problems

[jfbus]

simple-scan does not work with the Canon Pixma MX475 network scanner.

When running with debug output (simple-scan -d), I get the following error:

jfbus, thank you for reporting this and helping make Ubuntu better.

1) Did this issue start happening after an update, or has it always not worked with Simple Scan?
2) Is the problem reproducible when connecting to the scanner via WiFi and USB?
3) To see if this is already resolved in Ubuntu, could you please test http://cdimage.ubuntu.com/daily-live/current/ and advise to the results?

Hi Cristopher

Sorry for the late reply. I was on business trip and could not access the
web.
1) The scanner is new, I did not test with any previous Ubuntu
installation. The problem was present from the beginning
2 & 3) I will test as soon as possible and let you know
